--- Comment #1 from Kun Ge <iDingDong at outlook dot com> ---
I misplaced the wrong piece of codes.

the code that actually triggered the error is:

//---
#include <cstdlib>
#include <memory>

struct MemAttr {
        std::size_t size;
        std::size_t align;
};

template <typename T> constexpr MemAttr memAttrOf = MemAttr { .size =
sizeof(T), .align = alignof(T) };

template <MemAttr attr> using AlignedStorage =
::std::aligned_storage_t<attr.size, attr.align>;

template <typename T> using AlignedStorageFor = AlignedStorage<memAttrOf<T>>;
